NEW YORK – From New York to California, outrage over the verdict in George Zimmerman’s murder trial poured from street demonstrations and church pulpits Sunday as protesters spoke out against his acquittal and demanded federal charges on civil rights violations.

Protests were planned later Sunday in Boston, Detroit, Baltimore, San Francisco and other cities over the Florida case, which unleashed a national debate over racial profiling, self-defence and equal justice. At least one protest in California hours after the verdict late Saturday ended with vandalism.

In Manhattan, congregants at Middle Collegiate Church were encouraged to wear hooded sweatshirts in the memory of Trayvon Martin, the unarmed black teenager who was wearing a hoodie the night he was shot to death in February 2012.

The Rev. Jacqueline Lewis, wearing a pink hoodie, urged peace and told her congregation that Martin Luther King Jr. “would have wanted us to conduct ourselves on the highest plane of dignity.”

But, she added, “we’re going to raise our voices against the root causes of this kind of tragedy.”

Congregant Jessica Nacinovich, wearing a hoodie, said “I can’t help but want to express disappointment and sadness in response to the decision, and I just wanted to come and be here with everybody in solidarity and talk and pray and sing about where we go from here.”

At a youth service in Sanford, Fla., where the trial was held, teens wearing shirts displaying Martin’s picture wiped away tears during a sermon at the St. Paul Missionary Baptist Church.

WATCH: Marchers took to the streets of Washington, D.C. early Sunday morning to protest the not-guilty verdict in the George Zimmerman murder trial.

In Florida, about 200 demonstrators marched through downtown Tallahassee carrying signs that said “Racism is Not Dead” and “Who’s Next?”

In Chicago, black clergy members called for calm, with the Rev. Ira Acree of Greater St. John Bible Church saying the community should become “a united voice for peace” because it can’t control the verdict but it “can control our streets and communities.”

About 200 people turned out for a rally and march in downtown Chicago, saying the verdict was symbolic of lingering racism in the United States.

Seventy-three-year-old Maya Miller said the case reminded her of the 1955 slaying of Emmitt Till, a 14-year-old from Chicago who was murdered by a group of white men while visiting Mississippi. Till’s killing galvanized the civil rights movement.

Miller said she feels as if “nothing has changed in 58 years.”

The NAACP called for the opening of a civil rights case against Zimmerman in an online petition addressed to Attorney General Eric Holder.

Civil rights leaders, including the Revs. Jesse Jackson and Al Sharpton, urged peace in the wake of the verdict. Jackson said the legal system “failed justice,” but violence isn’t the answer.

But not all the protesters heeded those calls.

In Oakland, Calif., some angry demonstrators broke windows, burned U.S. flags and started street fires. Some marchers also vandalized a police squad car and used spray paint to scrawl anti-police graffiti on roads and Alameda County’s Davidson courthouse.
